@inproceedings { correia17, abstract = {This paper describes the AMIGOS project that is investigating the role of social interactions, emotions and adaptation in robots interacting over long periods with a group of users, thus contrasting to the typical one robot one-user paradigm in Human-Robot Interaction (HRI). In this paper, we present the initial work of the AMIGOS project and describe two studies conducted with autonomous robots acting in groups (composed by humans and robots) in an entertainment scenario. The first study explores the trust levels towards a robotic partner in a team game, and how it differs from trust levels towards a human partner. Results suggested the trust towards a robotic partner was linked not only with performance aspects, but also with other factors (e.g. previous knowledge/interaction). In the second study, we analysed team formation and team preferences in the same team game scenario, where two autonomous robots, embedding personalities with different goal-orientations, were both opponents and partners of the participants. We believe the results from both studies yield important findings within the goals of the AMIGOS project, and more broadly, for the area of human-robot groups.}, booktitle = {IEEE International Symposium on Robot and Human Interactive Communication Workshop on Groups in Human-Robot Interaction}, keywords = {Social Robotic Companions;}, month = {August}, title = {Groups of Humans and Robots: the AMIGOS Project}, year = {2017}, author = {Filipa Correia and PatrĂ­cia Arriaga and Sofia Petisca and PatrĂ­cia Alves-Oliveira and Raquel Oliveira and Samuel Mascarenhas and Iolanda Leite and Francisco S.
